As the name implies, the miniature cooling fan is a small and mini cooling fan. It is applied in a small space. With the development of science and technology, the more convenient the equipment we require, the better. Therefore, the application of the miniature cooling fan will become more and more extensive. Today, let's discuss the noise factors of the miniature cooling fan. We all know that the noise of the miniature cooling fan is relatively smaller than that of the large size. So what factors are related?
As the name implies, the miniature cooling fan is a small and mini cooling fan. It is applied in a small space. With the development of science and technology, the more convenient the equipment we require, the better. Therefore, the application of the miniature cooling fan will become more and more extensive. Today, let's discuss the noise factors of the miniature cooling fan. We all know that the noise of the miniature cooling fan is relatively smaller than that of the large size. So what factors are related?
1. Bearing: The noise of the bearing factor cannot be ignored. It is the biggest noise source. In general, the noise of the double ball bearing fan is much larger than that of the oil bearing fan.
2. Friction: When the miniature cooling fan is used for too long, there will be some situations such as unstable center of gravity, which will cause the fan blades and the fan housing to collide or rub, resulting in noise.
3. Speed: This is also an essential factor. The higher the speed, the higher the noise.
4. Air flow: During the rotation of the fan blades, they will be subjected to resistance in the air. The faster the rotation, the larger the fan blade area and the greater the resistance, so the noise will not increase unexpectedly.
Of course, these are the sources of noise that we cannot ignore. What are the tips for reducing the noise of the cooling fan?
1. Clean the dust of the cooling fan with a soft brush regularly.
2. Cushioning and shockproof. In addition to being fixed and strong, it can also increase buffers such as thin cloth and rubber pads at the contact position.
3, combined with the corresponding equipment to reduce the speed of the fan
4. Add lubricant to the cooling fan
5. Choose brands with high quality and credibility, which are expensive and expensive.
